Circulation & Paving

Description

Site circulation refers to the movement of people through an area. Landscape architects will analyze site circulation to understand how people use their environment and design solutions to help them better navigate their surroundings.
Paving is used to delineate paths for resident and staff travel. Paving is used for walkways throughout developments connecting parking areas, sidewalks, and seating areas to buildings. Paving is used for vehicular pathways; paving is also used for recreational areas. Whenever paving is used, preference is for more porous paving solutions that help reduce hardscapes in developments and aid in site drainage. Paving should be designed with resident input for colors and patterns with preference for variation to help create a distinct character for individual campuses and developments. Materials for paving are asphalt, concrete, stone, rubber, and porous bound materials.

Baseline

Care should be taken to separate open spaces designated for active or passive uses with fences, low walls and plantings. This is an effective way of helping people navigate naturally through a NYCHA campus. [CCG]
Design pathways that are convenient, intuitive, and enjoyable. Pathways should be designed to create sightlines through the development. [CCG]
Circulation on and through NYCHA campuses should be clearly defined, appropriately sized, and safe for pedestrians and cyclists while balancing vehicular access needs. When combined with other design strategies, such as materials, wayfinding, fencing and lighting, pathways can be convenient and enjoyable means to connect people with their destination. [CCG]
Internal pathways should be designed with consideration of who is using them and for what purpose, to prevent conflicts between modes of transportation and create a system that works for all the activities throughout a campus. [CCG]
Strategic use of barriers to maximize readability of circulation pathways and minimize defensive design can make residents and visitors feel welcome when entering a NYCHA campus. Barriers are crucial determinants of privacy and should be placed to encourage activity within primary areas of circulation and limit use of more intimate spaces within a campus [CCG]
Multi-functional barriers, such as hedges, could serve both as a soft barrier and as an ornamental plant, or a low wall that separates two differently used spaces could also serve as a seat.
Barriers should be designed with appropriate height, material, and transparency for the degree of privacy warranted in the space. Limit use of high fences that inhibit visibility and can be perceived as unwelcoming. [CCG]
Seating, lighting and signage on barriers can make campuses more inviting. [CCG]
Low maintenance solutions are preferred, especially if those spaces have limited uses for residents. [CCG]
Appropriate fencing placement is useful to decreasing the amount of time spent on maintenance of a space. [CCG]
For effective control of surface water flow, the pitch for positive drainage must be at least one foot rise over one hundred feet run (1%) and should be less than one foot rise over fifty feet (2%) run. Pitched surfaces steeper than 5% slope must follow ADA design criteria for ramps.
There should be a clear distinction among pathways and internal streets within a campus depending on their use. Pathways should be for pedestrian use only unless vehicular access is needed by Operations staff or emergency vehicles. [CCG]
Internal streets should clearly delineate bike paths to ensure they are respected by vehicles and pedestrians.
Pathways where vehicular use is allowed within the campus should be clearly marked with appropriate signage and crosswalks for pedestrians. Street furniture (such as bollards, curbs, and planters) can slow down or prevent vehicular circulation in a pedestrian zone. [CCG]
Different materials are used to differentiate pathways and roads. [CCG]
Vehicular circulation in the interior of NYCHA campuses should be minimized. Where it is necessary for operations staff or emergency vehicles, traffic calming methods (such as bollards, speed bumps, chicanes, etc) should be used, and pedestrian crossings should be clearly marked and signed.
Utilize a variety of materials to reinforce a sense of place. [CCG]
The palette of materials used throughout a campus should be visually engaging, durable and easy to maintain. Materials should support accessibility for people with disabilities, children, and seniors. Material selection affects the way spaces may be used. For instance, a paved space can better serve as an area for a children’s game of double-Dutch, while a grassy space is more conducive to picnics. Adding colors, textures, or similar materials in different patterns help achieve visual variety and differentiate adjacent areas. [CCG]
Small areas of ‘special’ paving with extra technical function or aesthetic value can be a cost-effective way to expand the material palette.
Only use asphalt paving for basketball courts and playgrounds. Safety surfacing or surface color paint can be installed in conjunction with asphalt paving. Asphalt paving should be avoided elsewhere for several reasons, including reduction of the “heat island” effect. Instead of asphalt, designers are urged to use concrete pavers for walkways, vehicular access and parking areas, seating areas, building entrances, and gathering areas.

Stretch

Designers are encouraged to use light-colored, high-albedo materials, with a minimum solar reflectance of 0.3, over at least 50% of the site’s paved area.
Use of porous material to aid in site drainage, are encouraged for sites in high flood risk zones or if project budget allows the use of these materials.
In general, designers should seek to reduce the overall paved area of the site.

Community Gardens

Description

A community garden is a place where the resident community can come together to grow a garden. Spaces within the garden are dedicated to growing fresh vegetables and cut flowers, as well as tool storage, and learning spaces with opportunities to gather and grow. There are many community gardens within and adjacent to NYCHA campuses that are overseen and maintained by resident groups. Community gardens are also an important space for younger residents to spend time outside and work with the soil while learning about nature, agriculture, and permaculture. The gardens support active communities and learning while beautifying the campuses with minimal maintenance from grounds staff. Across the city, there are over 600 resident gardens tended to by more than 1,000 NYCHA residents. [CCG]

Stretch

Support gardens by providing access to water and space as well as facilitating connections to community partners who provide educational and material resources for residents.
Residents should be consulted on locations and design for Community Gardens. They should be built in areas with adequate sunlight and in locations that are accessible to residents.
If an improvement to a community garden is part of a broader site improvement, designers should consult the Directive 10 regulation of the NYC Office of Management and Budget to understand items that are eligible for funding. The improvement of a community garden must include a comprehensive betterment, as defined in Directive 10, and meet the $35,000 minimum cost eligibility for each area.
Vegetable gardens should use raised beds meeting the following requirements:
2×10″ lumber for planter boxes, preferably cedar; no treated lumber
Minimum height 20″ for accessible planters
Use raised bed planters for vegetable gardens
Source water from building basements using the NYCHA standard hose bibb detail with security lockbox.
Gardens should be located in an area with good sun exposure. [CCG]

Excavation

Description

Excavation and backfill are used to prepare ground for site improvements, including building foundations and slabs, walking surfaces, perimeter and underfloor foundation drainage systems, and underground mechanical and electrical utilities.
Title 24 Code of Federal Regulations (CFR) Parts 50 and 58 (24 CFR Part 50 or 24 CFR Part 58) state that “All property proposed for use in HUD programs be free of hazardous materials, contamination, toxic chemicals and gasses, and radioactive substances, where a hazard could affect the health and safety of occupants or conflict with the intended utilization of the property.” As part of a National Environmental Policy Act (NEPA), State Environmental Quality Review Act (SEQRA) and/or City Environmental Quality Review (CEQR) environmental review, projects may be required to perform soil and site investigation to ensure that there are no new potential pathways for contamination as a result of a project.

Baseline

Details (site restoration, tree protection, erosion control, traffic control).
Drawings must indicate the locations of all utilities.
Material test reports must be performed in accordance with DOB requirements.
Trench and excavation walls must be supported by adequate sheeting and properly braced.
Surface water and subsurface or ground water must be prevented from flowing into excavations and from flooding project sites and surrounding areas.
Utilities must not be constructed or laid in a trench in the presence of water. All water must be removed from the trench prior to placing the line.
Before backfilling, all water distribution piping systems (including sewer, stormwater, steam, condensate carrier) must be hydrostatically tested and inspected. Similarly, gas piping, valves, fittings, support structures, anti-corrosion equipment and associated underground components must be inspected and tested before backfill is put in place.
All material for backfilling must have a moisture content and gradation suitable for attaining the required density, must be free from frost at the time of placement, and must be free from boulders.
Miscellaneous fill material removed from the trenches and excavations will not be considered as acceptable backfill material unless found acceptable and approved in writing.
In general, it is expected that material excavated from a trench must be used to backfill only the upper portion of the trench. Such material must not be used to backfill the lower portion of the trench.
Select granular fill material must be placed in the lower portion of the piping trenches.
Clean fill material must be used when there is a deficiency of acceptable backfill.
Cathodic protection must be installed for corrosion control of all buried metallic piping.
The trench for installation of electrical underground conduits and cables must be 24 inches deep minimum as is required by NEC. The bottom of the trench must be free of loose or projecting stones and debris. Backfill must be sand or screened earth free of stones and sharp objects. Backfill must be compacted to specified density to avoid settling.
Provide installation of Buried Utility Warning Tape above underground utilities. Tape’s color and lettering must be unaffected by moisture and other substances contained in the backfill material.
It is recommended that underground warning/marking tape be buried at a depth of 12 in (30 cm) or less below grade.
Underground conductors must be identified for the voltage and conditions under which they are installed.
When soil and site investigation is required as part of an environmental review, the project team would need to at a minimum provide a Phase I Environmental Site Assessment (Phase I ESA) which identifies potential or existing environmental contamination liabilities. Current standards for a Phase I is the American Society for Testing and Materials E1527-21 (ASTM E1527-21) but are subject to change. This Phase I ESA will be reviewed by NYCHA for concurrence.
If the result of the Phase I ESA indicates potential contamination or areas of concern, or NYCHA suggests, a Phase II Investigation Work Plan would be required to outline the proposed scope of work for soil, groundwater, and/or soil gas evaluation. This Phase II Investigation Work Plan should be accompanied by a Health and Safety Plan (HASP). These reports will be reviewed by NYCHA and potentially by NYC Department of Environmental Protection (DEP) for accuracy and concurrence.
Once the Phase II Investigation Work Plan and HASP are reviewed and approved by NYCHA and/or DEP, the investigation activities may take place. The results of the investigation should be summarized in a Phase II Environmental Site Assessment (Phase II ESA).
Depending on the result of the Phase II ESA, the project team should be prepared to put together a Remedial Action Plan (RAP) and Construction Health and Safety Plan (CHASP) that outlines what remedial measures that would likely be required to adequately mitigate the contamination. The Phase II ESA, RAP, and CHASP will all be subject to review and approval from NYCHA and/or DEP.

Exterior Security

Description

NYCHA campuses are first and foremost homes. Exterior security should serve to enhance the wellbeing of residents and to foster a sense of safety. To that end, care should be taken in the design of exterior security so as not to give the impression of hostility to residents.
Security at NYCHA properties is achieved through design principles focused on ensuring natural surveillance and providing consistent observation. Access control design and territorial enforcement establish clear boundaries within areas and strengthen feelings of ownership. Maintenance and management are critical to fostering “pride of place”, attracting more wanted activities at NYCHA. Other security paradigms including ‘eyes on the street’, Crime Prevention through Environmental Design (CPTED), traffic calming, and street level activation should be applied as appropriate.
Residents and staff should be consulted in the identification of security concerns and in the implementation of proposed solutions.

Signage Grounds

Exterior Signage

Description

Wayfinding panels are used on large campuses to help people understand where they are and how to access any location within the campus. These can be broadly helpful in NYCHA campuses where entrances to buildings and resident amenities are not accessed from the street. [CCG]
Wayfinding systems typically include a map of the area with labels identifying building addresses and important open spaces, amenities, or services, in addition to other visual markers with universally known symbols. [CCG]
Wayfinding systems are most effective when placed in highly visible locations, such as near entry points of a NYCHA campus, or near a community space with pedestrian traffic. Providing good illumination on a wayfinding panel eases its readability and use after dark. [CCG]
Signage for rules and regulations should be clearly visible and appropriately located.

Baseline

Exterior signage shall not be erected in a manner that would obstruct the view of official traffic signs, signals, or devices. Signs and sign support structures shall be kept in repair and in proper state of preservation and they shall be designed and constructed to withstand wind pressure.
Signs attached to masonry, concrete or steel shall be safely and securely fastened to safely support the loads applied.
Provide signage in multiple languages (per local needs) indicating age-appropriate use at playgrounds.
Install NYCHA standard signage at parking.
Develop educational signage and maintenance cards to facilitate communication at erosion and stormwater control features within campuses.
Entrances should include address signage wherever possible.
Provide building identification signage with lighting for nighttime visibility. [COMPMOD]
Provide exterior site identification and wayfinding signage. [COMPMOD]
Provide exterior site identification and wayfinding signage. [CCG]
Clearly mark access points to building lobbies, community centers, laundry facilities, management offices, and highly-used open spaces, such as gardens, playgrounds and sports courts. [CCG]
Consider different wayfinding strategies (such as pavement stenciling, sculptures, and colors or unique features) to decrease confusion on larger sites. [CCG]
Clearly mark pathways where vehicular use is allowed within the campus with appropriate signage and crosswalks for pedestrians. [CCG]
Highlight building addresses so they are visible from a distance. Creative signage can also add to the sense of ownership for residents who primarily identify with their building. [CCG]

Stretch

Install murals, memorials, or tributes to former or current community leaders who had a positive effect on the neighborhood. [CCG]
Install signage commemorating special personalities, window décor that reflects personal heritage, and community spaces that display. [CCG]
Install wayfinding and clear communication signage for residents to help get household trash, recyclables, compost, and bulk waste to their proper destinations. [SA]

RAD Conversion

RAD Conversions should assume new comprehensive and cohesive building signage and campus wayfinding.
Building signage should meet all requirements of the Housing Maintenance Code (contained in the NYC Administrative Code), Multiple Dwelling Law, NYC Zoning Resolution, and the Rules of the City of New York.
At closing, NYCHA Property Management will remove all signage that includes specific NYCHA contacts or procedures. Typical NYCHA Property Management signage to be updated or replaced may include:
- Development name signage (exterior)
- Building address signage (exterior)
- No loitering (interior)
- No smoking (interior)
- NYCHA rules (interior)
- Garbage disposal procedure (interior)
- Customer Contact Center details (interior)
- Lead (Interior)
Campus wayfinding should build on strategies identified in the Connected Communities Guidebook towards creating a unified wayfinding system to help people navigate the campus. Wayfinding panels are used on large campuses to help people understand where they are and how to access any location within the campus. These can be broadly helpful in NYCHA campuses where entrances to buildings and resident amenities are not accessed from the street. Wayfinding systems typically include a map of the area with labels identifying building addresses and important open spaces, amenities or services, in addition to other visual markers with universally known symbols.
Wayfinding systems are most effective when placed in highly visible locations, such as near entry points of a NYCHA campus, or near a community space with pedestrian traffic. Providing good illumination on a wayfinding panel eases its readability and use after dark.

RAD Conversions

RAD Conversion projects should refer to the Connected Communities Guidebook for general site planning principles as they develop their approach to landscape and open space design. Property Assessments, Design Workshop Summaries, and “What We’ve Heard” documents should be reviewed closely, as they contain site-specific priorities and recommendations from NYCHA, its architectural services consultants, and residents. NYCHA assumes that landscape and open space design will also respond to resiliency needs and will be coordinated with existing and planned Green Infrastructure features.
RAD Conversion projects will be asked to engage residents on landscape and open space design and to develop design over the course of pre-development through design charrettes and other visioning workshops. Sites & grounds scope cannot be determined after closing.

On-site Clean Power Generation & Battery Storage

Description

Onsite clean power generation is the production of clean energy (solar, wind, hydro, among others) at the site where it is to be consumed. It is a form of decentralized energy generation that often substitutes or complements the energy received through the utility grid. The ideal siting for solar installations it’s in areas with difficult distribution e.g., rural, or areas with high-dependency on fossil fuel-based power generation e.g., New York City. In addition, solar PV system hosts require sunlight exposure; reason why NYCHA’s footprint size makes it an ideal for solar generation within NYC.
The elements for Onsite clean power generation are:
- Solar array, which is a group of interconnected solar panels, each panel has a group of cells
- Inverter, which transforms DC electricity into AC (for either building use or to the grid)
- Meter, indicates power consumption and that is received/transferred to the grid
- Battery for storing the power generated by the PV system
Onsite Clean Power Generation can either:
1. Serve directly the grid, for which it does not need a battery
2. Serve the site where it is installed, for which it would need a battery
3. Serve both, the site and the grid, and would need a battery
Of the three options listed above, NYCHA currently has a program (ACCESSolar) for number 1. The other two uses of solar PV systems require a battery which is known as Battery Energy Storage Systems, or BESS. These are rechargeable batteries that store energy from different sources –ideally from clean sources like solar- and discharge it when needed. BESS consists of one or more batteries used to balance the electric grid, provide backup power, and improve grid stability. BESS can serve multiple purposes:
- Resiliency or Emergency Generation: means a secondary source of electrical power whenever the primary energy supply is disrupted or discontinued during power outages or natural disasters that are beyond the control of the owner or operator of a facility.
- Grid support: If BESS is connected to the grid, the batteries can store energy during low-demand hours in order to serve the grid at peak hours. As the energy stored comes from the grid, this can come from different sources, and its role is just storing.

Baseline

Upgrade to standard solar PV [COMPMOD]
- Install solar PV only on buildings that will maximize investment.
- Assume battery storage or community microgrid where possible.
- Panels are installed on NYCHA’s roof, but power is returned to the grid and NYCHA receives the proceeds of that power.
- Unless the site has special maintenance provisions through the Trust, installation of any array for community solar must be closely coordinated with NYCHA’s Sustainability Programs team.

Stretch

Provide back-up power for all community facilities. [COMPMOD]

RAD Conversions

RAD Conversions should submit a report evaluating options to provide on-site solar and back-up power for community facilities and residential buildings. The solar report should reference the path to electrification plan and consider solar as a means of facilitating electrification. Solar infrastructure can be proposed as part of the RAD Conversion Project Scope of Work or by procuring a third-party installation. The report should include financials (up-front costs, rebates or incentives, savings, payback) and outline the rebate and incentive application strategy. Sightline studies should be conducted, as applicable. If on-site solar use is determined to not be feasible, the RAD Conversion must allow for leasing its roof space for community solar.
RAD Conversion should include the feasibility of demand response implementation for the backup power or other readiness measures. Learn more here: CPower Brochure.pdf

Parking Lots

Description

Parking lots for residents and NYCHA vehicles are needed to allow for mobility and servicing of grounds including maintenance and cleanup. NYCHA parking lots have historically been paved with asphalt, however light-colored (high-albedo) materials are preferred for any new work. Typical work includes new pavement, vehicular drop curb, striping, signage, wheel-stops, guardrails, vehicle access controls, ADA parking spaces, and accessible ramps to walkways.
Related work includes installation of security cameras and earthwork.

Baseline

When scope of work includes parking, external regulatory guidelines must be meet the regulations of: NYC DOT, NYCHA (including standard lighting and signage), UFAS, NYC Building Code, ADA/VCA and ADAAG.
New parking lots should include accessible ramps for residents, with appropriate curb cuts.
Parking spaces should be maintained with clear lines of sight and no obstructions.
Fixed bollards should be located at entrances.
Lots must contain required drainage and meet all requirements for storm water management based on area of site disturbance. Filings should be made to NYC DEP for Storm Water Management plans.

Stretch

When possible, permeable pavements should be used for improved site drainage. When specifying permeable pavements, maintenance of permeable function should be considered and planned for.
Where space allows, parking lots should designate charging stations for electric vehicles, micro-mobility, and battery back-ups. If solar charging stations are proposed, they should be in areas free of obstruction and trees that would shade panels. Any proposals to this effect must be coordinated with NYCHA.
Where possible, standard bicycle racks should be provided at a minimum number of 1 bicycle parking space per 10 car spaces. When funding allows and residents support, secure bicycle parking should be provided.

When designing site work, care should be taken to separate open spaces designated for active or passive uses with fences, low walls and plantings. This is an effective way of helping people navigate naturally through a NYCHA campus. [CCG]
Strategic use of barriers to maximize readability of circulation pathways and minimize defensive design can make residents and visitors feel welcome when entering a NYCHA campus. Barriers are crucial determinants of privacy and should be placed to encourage activity within primary areas of circulation and limit use of more intimate spaces within a campus [CCG]
Multi-functional barriers, such as hedges, could serve both as a soft barrier and as an ornamental plant, or a low wall that separates two differently used spaces could also serve as a seat.
Barriers should be designed with appropriate height, material, and transparency for the degree of privacy warranted in the space. Limit use of high fences that inhibit visibility and can be perceived as unwelcoming. [CCG]
Seating, lighting and signage on barriers can make campuses more inviting. [CCG]
Low maintenance solutions are preferred, especially if those spaces have limited uses for residents. [CCG]
Appropriate fencing placement is useful to decreasing the amount of time spent on maintenance of a space. [CCG]
For effective control of surface water flow, the pitch for positive drainage must be at least one foot rise over one hundred feet run (1%) and should be less than one foot rise over fifty feet (2%) run.
Pitched surfaces steeper than 5% slope follow ADA design criteria for ramps.
There should be a clear distinction among pathways and internal streets within a campus depending on their use. Pathways should be for pedestrian use only unless vehicular access is needed by Operations staff or emergency vehicles. [CCG]
Maintain a clear distinction among pathways and internal streets within a campus depending upon their use.
Pathways should be for pedestrian use only unless vehicular access is needed by Operations staff or emergency vehicles. Pathways can also be used for children under the age of 12 who are biking. [CCG]
Clearly delineate bike paths on the internal streets and ensure they are respected by vehicles and pedestrians. [CCG]
Clearly mark pathways where vehicular use is allowed within the campus with appropriate signage and crosswalks for pedestrians. [CCG]
Place street furniture (such as bollards, curbs, and planters) to slow down or prevent vehicular circulation in a pedestrian zone. [CCG]
Use materials to differentiate pathways and roads. [CCG]

Planting

Description

Refers to the design and installation of topsoil, humus, fertilizer, mulch, and new plantings of trees, shrubs, groundcover, lawn. Planting provides shade during hot weather, mitigates wind in large open areas, reduces soil erosion and stormwater pollution, and is an important habit for songbirds and insects. Planting design provides areas for rest and refuge for residents and provides access to nature for residents and community members in areas often lacking parks and open outdoor spaces.
The mature tree canopy at many NCYHA campuses is one of our greatest assets. It is virtually irreplaceable and contributes to the sustainability of New York City as a whole. Preservation and protection of these mature trees must be prioritized in all design and construction work. (Reference this doc: NYCHA_Urban_Forest.pdf)

Baseline

Consideration should be given to balancing soft and hard materials to enhance the appearance and functionality of NYCHA campuses. Consideration should also include crime prevention and pest management where the problem exists. [CCG]
Where possible a variety of planting should be incorporated into the grounds to minimize lawn in favor of perennials and trees. Planting design should vary by campus to help instill differences for various developments and give open spaces character. It ties together hard and soft materials to create pleasant and attractive open spaces. Easy to maintain plantings are preferred to allow ease of maintenance and preserve the appearance and upkeep of green open spaces which affects the perception of the community, resident pride in their home, and employee morale. [CCG]
Variation across the campus is also important to favor different areas based on local geography, soil condition, and micro-climate. Landscape can be used to help residents and non-residents navigate campuses. Since landscaped areas cover over half of NYCHA grounds and provide access to green open spaces in areas of the city in need of greater access to open space. The social value of landscaped areas for residents is highlighted when residents become attached to them. Some campuses have named them, such as “Shadyside” in Brownsville or “Cherry Park” in Woodside, adding cultural identity to these areas. [CCG]

Stretch

Designers are encouraged to include irrigation in planting projects where project budgets allow. In such cases specify plants that require 1–2 years of irrigation after planting.
Irrigation systems should favor passive drip irrigation below the surface or running along the surface to reduce maintenance and water loss.
Preference is for the use of native plants or plants well suited to the local micro-climate for water conservation. Designers are encouraged to specify plants that are non-invasive, attractive, and low maintenance, and diverse and non-invasive tree species adapted for present and future site conditions (e.g, planting salt tolerant species in areas prone to coastal flooding).

Playgrounds

Description

Playgrounds, General
- Multi-generational play spaces are needed to respond to demographic shifts in public housing residents. As younger families move into developments and residents age in place varied playgrounds are needed to cater to different age groups. Active play spaces for toddlers, school age children, teenagers, and adult fitness areas, and new and innovative play equipment and landscape features that incorporate vegetation, and natural elements all provide a sense of place and an important amenity to residents.
- Playgrounds for young children should include seating for adult caregivers.
- Playground work includes new pavement and color-wearing surface, safety surfacing, play or adult fitness equipment, fencing and accompanying site furniture in the play area – including seating, waste receptacles, and drinking fountains. The project can include spray showers, activators, valves, and controls, plumbing connections/systems, trenching, and restoration of grounds.
- When playgrounds are specified for open spaces, they should involve significant resident input on proposed designs. Playgrounds must support a full range of social, physical, and educational opportunities for children of different ages and abilities, while also offering a comfortable environment for their families, caregivers and older residents.

Spray showers, water moving features, and fountains
- Spray showers, water moving features, and fountains keep residents cool during hot summer months and provide potable drinking water for residents in play areas and outdoor spaces. With large open campuses and many recreation spaces for adults and children, water elements are critical for staying cool and hydrated and should be incorporated where water supplies and water pressure allow for subsurface connections.

Sport Courts
- Active play and recreation spaces for children and adults are a core element for better health and well-being of residents. A diversity of sports courts should be incorporated where funding and space allow. These courts are often a cornerstone to development and can form the identity of a neighborhood where tournaments are enjoyed by residents and the surrounding community. Sports are an important bridge to encourage more active use of open spaces and campuses by the community. The work for sports courts includes earthwork, new pavement and color-wearing surface, athletic equipment, fencing, sports lighting and electrical connections/systems, and site furnishings.

Baseline

Playgrounds, General
- Playgrounds should be designed for specific age groups: pre-school (2 to 5 years), school-age (5 to 12 years), teenage (12 to 18 years), and adult fitness zones. Play areas are to be designed with separate areas dedicated to specific age ranges – mixing equipment in the same area is discouraged. Given the size of most campuses, separated play areas for specific age groups can be accomplished.
- Playground surfacing must comply with ASTM standards for fall zones. When possible, safety surface should be multi-colored to allow patches and replacements over the lifespan of the surface to visually blend with the surrounding material.
- Locate all playgrounds along accessible routes.
- Provide adequate room for circulation by the non-ambulatory among pieces of play equipment.
- Include signage in multiple languages (per specific development and resident needs) indicating age-appropriate use.
- Design durable and low-maintenance play areas.

Spray showers, water moving features, and fountains:
- Locate near athletic fields, playgrounds, and other active areas
- Include spray showers where existing playgrounds are retrofitted or renovated.
- When existing spray showers are replaced, existing plumbing should be inspected and updated if necessary.
- Controls for the spray showers must utilize non-electric, mechanical control with a water-saving timer mounted on the unit.
- Playground spray units must be powder-coated steel.
- Plumbing must be installed below frostline (3 feet or deeper) and winterized where pipes must be insulated without shut-off valves for winter.
- All controls and valves must be in the nearest basement and secured so they are only available to site staff.
Sports courts
- Use open plan design principles to provide maximum visibility throughout the area.
- Athletic area surfacing should be appropriate to the activity: for basketball courts, use slip-resistant, acrylic-colored surface on top of pavement; for baseball, use natural or artificial turf.
- Bleachers in athletic areas must be made of metal. The underside of bleachers should be open to view. Existing concrete seating may be refurbished but concrete should not be used for new installations.

Stretch

Alternative play spaces are encouraged for active play and variety of community uses across campuses, so each play area functions for a distinct use or user group. Examples of additional play spaces are pump tracks, parkour areas, and skateboarding ramps.
Place new active recreation spaces in highly visible locations and provide lighting opportunities to extend hours of usability. [CCG]
Partner with organizations focused on play and fitness, including sports programming leagues, to create or upgrade playgrounds and adult fitness equipment areas, such as Fathers Alive in The Hood (FAITH) or the Police Athletic League. [CCG]
Engage residents in the design of the spaces, as they may have recommendations related to their look and feel, or equipment choices. [CCG]

Site Amenities

Description

Amenities for residents include various types of benches and seating, tables, bleachers, waste receptacles, trashcans, BBQ grills, planters, bollards, and storage sheds.

Baseline

Seating should be included in any ground or open space work. Seating locations should be selected in consultation with residents and located where there are natural points of rest around the campus, such as near bus stops, community centers, and gathering spaces. [CCG]
Locate seating areas to enhance comfort and by considering placement of seating areas under trees for natural shade during the summer, or protected from the wind buffeting during the winter, and protected from nuisances (noise, traffic pollution). [CCG]
Where possible and subject to resident approval, benches should be all-steel, powder-coated in lighter colors, or with recycled plastic lumber seat and back, and located near trees, shade, and other communal gathering areas.
Game tables must be accessible to everyone, and at least one of them should be wheelchair accessible. Preference is for long-lasting game tables in precast concrete, mounted on concrete or on a concrete-filled steel pipe pedestal, and set in a concrete foundation.
Bicycle racks should be installed near entrances and pedestrian routes, and in high-visibility areas not blocked by plants or other amenities.
Provide dedicated resident recycling stations for each building and locate for convenience, near building entrances where possible and subject to resident approval.
Note: Residents can call 311 to request the Department of Transportation (DOT) for benches on a public street surrounding a NYCHA campus. Small businesses and non-profit organizations can apply to the DOT’s Street Seats program in front of a non-residential ground-floor space. [CCG]

Site Fences

Description

Site fences are used to enclose active play areas, to delineate pedestrian spaces from planted areas, or to discourage traffic across campuses. NYCHA is shifting away from the use of site fences to protect lawn areas and spaces. Where possible designers should use plantings, seating, low fences, or similar soft visual barriers to delineate spaces.
Permanent site fences are installed as part of projects and must adhere to NYCHA standards for durability and ease of maintenance.
Permanent site fences may be used strategically. For example, a fence around the perimeter of a NYCHA site may be used to control access and encourage desired circulation paths, or a fence around a waste yard may serve both a screening and security function.
Temporary fences are installed during the construction phase of a capital project to ensure resident safety. Temporary fences are mandated by the NY Department of Buildings and subject to their requirements.

Baseline

Temporary construction fence is required by the NYC Building Code to protect the public against possible hazards related to ongoing construction, such as new building, areas of demolition, open excavation or extensive alteration.
Fence installation may be of solid material such as wood, corrugated metal, or other suitably rigid and strong materials.
The fence or gate shall be constructed of woven, galvanized steel wire mesh and shall be of sufficient strength and rigidity to prevent access to the site.
The fence or gate shall be covered with an opaque sturdy cloth “windscreen” fabric or equivalent netting at all locations. Fabric or equivalent netting shall be securely attached to the fence or gate in accordance with manufacturer specifications.
A fence shall be at least 8 feet high.
Posts (including concrete encasement of posts), frames, braces, and rods erected at design intervals to resist the effects of wind and secure the entire length of fence.
Posts shall be of galvanized steel pipe of a diameter that provides rigidity. Posts shall be suitable for setting in concrete footings, for driving into the ground, or for inserting in precast concrete blocks.
Viewing panels (openings 12”x12”) should be provided in the solid fence that allow a site to be viewed from outside of the fence.
A project information should be displayed on a fence. Information panels should be constructed of durable, weatherproof, flame-retardant material such as vinyl, plastic, or aluminum.
Permanent construction fences should be robust and resistant to vandalism. The design should use elements that are easy to match and replace if damaged.

Stretch

Approved artwork or alternative artwork, selected by the NYCHA shall be displayed on temporary protective structures such as sidewalk sheds, construction fences, and supported scaffolds that will be installed for at least 90 days.

Site Lighting

Description

Site lighting includes all lighting across the campus. Exterior lighting is provided at entry ways, court yards, walkways, grassy areas, property perimeter, parking lots and uplighting for signage and planting, etc. Site lighting types may be poles, surface mounted fixtures on building facades, fencing, signage or installed as bollards or landscape mounted.
New lighting should meet minimum lumen levels to provide adequate lighting for path illumination at night. LED fixtures are required for all new lighting to improve energy efficiency and replace older, fluorescent and metal halide lighting fixtures. Preference is for durable fixtures which focus on ease of maintenance.
Exterior site lighting serves to enhance safety and security by illuminating outdoor areas to deter crime, improve visibility for surveillance, and guide occupants safely. Effective design involves selecting appropriate lighting fixtures, positioning them strategically to eliminate shadows and blind spots, ensuring even illumination across the property, using energy-efficient and durable lighting technology, and incorporating motion sensors or timers for adaptive lighting control.

Baseline

Exterior lighting design should encourage street life and integrate NYCHA grounds with the surrounding community. Designers should limit the use of wall packs fixtures on residential buildings. Light fixtures should be as energy efficient as possible, promote ease of maintenance, and reduce light pollution.
Exterior lighting is required on pedestrian paths, near seating, play and athletic areas, in parking lots and along vehicular circulation paths, at building entrances, and on building facades.
EGC requirements:
- Minimum 40 lumens per watt
- Recessed light fixtures must be Insulation Contact Air-Tight (ICAT) models with ENERGY STAR LED.
- Exterior lights fixtures must be ENERGY STAR LED, Dark-sky-friendly, and must include motion sensor,
- Common-area lights must be LED and must include an occupancy sensor or bi-level control.
Exterior lighting controls shall comply with the requirements of the 2020 NYC Energy Conservation Code:
- Lights shall be automatically turned off when daylight is present and satisfies the lighting needs
- Lighting shall be controlled so that the total wattage lighting is automatically reduced by not less than 50 % by selectively switching off or dimming luminaires at one of the following times:
  - From no later than midnight (12a.m.) to no earlier than 6 a.m.
  - During any time where activity has not been detected for 15 minutes or more.
Exterior lighting shall be controlled by time-switch and should comply with the following:
- A clock shall be capable of being programmed for not fewer than 7 days.
- Shall be capable of being set for seven different day types per week.
- Shall incorporate an automatic holiday setback feature.
- Shall have program backup capabilities that prevent the loss of program and time settings for a period of not less than 10 hours if power is interrupted.
Luminaires serving outdoor parking areas and a mounting height of 24 feet (7.3 m) or less above the ground shall be controlled to automatically reduce the power of each luminaire by a minimum of 50 % when no activity has been detected in the area for a time of no longer than 15 minutes.

Stretch

Where possible, new lighting fixtures should contain integrated photovoltaic cells, photosensors, and astronomic time clock control.
These photovoltaic fixtures will provide outdoor lighting without requiring a substantial electrical supply.
These photovoltaic fixtures should be located away from buildings and outside of tree coverage to provide maximum available sunlight.
Where possible, new lighting fixtures should be chosen to comply with IDA and AMA recommendations to reduce light pollution and night-time exposure to blue-rich white light sources that disrupt sleep. Fixtures should be shielded to reduce glare and light trespass. Uplighting should not be used. Warmer temperature lightbulbs of 3000 Kelvin (K) or lower are preferred.

RAD Conversions

RAD Conversions should evaluate opportunities to improve site access and introduce additional site lighting to improve overall site security and safety.

Solar Roofs

Description

ACCESSolar (Accelerating Community Empowered Shared Solar) is a NYCHA-run program within the Asset & Capital Management Division, Sustainability Department, created in 2017. The Program has the goal of bringing to NYCHA and its residents the benefits from clean energy generation at zero cost by facilitating NYCHA-operated rooftops as site hosts of solar photovoltaic (PV) systems¹Environmental Justice Areas.
- Larger developments (number of buildings or roof squared footage)
- Preferably low-midrise (below 10 stories) but not restrictive to high-rise
- Active roof warranty
- Roofs in good conditions or recently replaced (not before than 2016)
NYCHA supports as site host and through technical reviews:
- Code compliance NEC, FDNY, among others applicable
- Preference for conduit run on the exterior of the buildings
- Structural assessment of weight placed on the rooftops, and safety
- Architectural review of overall design and attachments
- Interaction/interference of the system with other utility conduits
- Safety of egress and clearance for onsite staff to other roof equipment

Baseline

Layouts – Solar PV array layout should consider egress requirements, clearances for O&M of roof and elevator equipment.
Inverters – Inverters are preferred to be placed in enclosed areas away from tenant access. Warning signalization is required.
Conduit – Solar PV arrays are often connected at the rooftop; the conduit should be visible and be lay out in a way that prevents tripping hazards. The system makes its way from the roof to the meter/electrical rooms (often located at the basement) through an enclosure for conduit, often between 3-7″ wide, which depends on the system size.
- The preferred location for the conduit is in the exterior of the building.
- If conduit cannot be run on the outside of the building, any interior runs must be code compliant and adhere to NYCHA’s policies and avoid resident interference or disturbance.
Structural loads – Wind loads and robust connections to existing slabs must be included in design.
Attachments – Like other mechanical installations (such as water tanks, HVAC, communications equipment), attaching PV panels to a rooftop demands careful detailing of the roofing system to prevent maintenance problems.
Security and Safety notices – Many NYCHA roofs are accessible via stairhall bulkheads. If a solar PV system is installed on a building, installers are required to post notice on the doored access.
If community solar work is being considered through CompMod or Trust, it must be closely coordinated with NYCHA’s Sustainability Programs team.

Stairs, Ramps & Railings

Description

Stairs and Ramps are used for circulation in and around buildings. Stairs provide access to the front of buildings and are located within the building to provide a safe means of vertical circulation and travel in the event of a fire. Following guidance from NYC DCP Active Design G uidelines stairs are encouraged for active mobility of residents and to reduce reliance on elevators which prolongs the useful service life of elevators. Ramps are utilized for access to lobbies and basements. Ramps provide accessible access and must conform to required slopes as specified by ADA Requirements.

Baseline

All stairs, stair landings, and corridors must be in accordance with the NYC Building Code to provide an accessible means of travel for the mobility impaired.
All ramps must have a running slope no steeper than 1:12.
Where possible ramps shall conform with the least possible running slope and, where possible, be located next to new or existing stairs. Maintain minimum distances between stairs and ramps to provide older residents and mobility impaired residents the quickest and most direct path of travel.
The minimum clear distance between handrails must be 36 inches (915 mm) or as otherwise stated in the NYC BC.
All ramps are required to have a landing at the top and the bottom of each ramp run.
The minimum landing clear length shall be 60 inches long.
Ramps that change direction between runs at landings are required to have a clear landing of 60 inches by 60 inches square as a minimum.
Ramp runs with a vertical rise greater than 6 inches are required to have handrails.
When installing drop curb ramps, counter slopes of adjoining sidewalks, gutters, and road surfaces immediately adjacent to the drop curb shall not be steeper than 1:20. The adjacent surfaces at transitions of drop curbs to walks, gutters, and streets shall be at the same level.

RAD Conversion

All RAD Conversions must comply with the accessibility requirements of all applicable laws including, without limitation, to the New York City Building Code, the Fair Housing Act, the Americans with Disabilities Act, Section 504 of the Rehabilitation Act of 1973 (“Section 504”), and the 2021 FHEO Assurances Agreement.

Stormwater Piping & Drainage Structures

Description

NYCHA stormwater infrastructure includes rain gardens, subsurface infiltration systems, and porous paving. NYCHA also supports right-of-way bioswales and stormwater green streets for adjacent DOT sites, but is not responsible for their designs, construction, or maintenance.

Baseline

Designs must follow NYC DEP Office of Green Infrastructure Standards, the New York City Stormwater Manual an appendix to Chapter 19.1 of Title 15 of the RCNY, NYC DEP Green Infrastructure, NYC Environmental Protection “Rain gardens”, NYC Environmental Protection Criteria for Detention Facility Design.
Relining of damaged or defective stormwater pipes, catch basins, stormwater inlets, manholes, etc. should be considered as an alternative to costly replacement.
Where applicable and feasible, use permeable materials for hardscaped areas, rain gardens, and bioswales to increase the retention of stormwater within campuses. The types of stormwater assets used and where they are sited need to be determined based on sub-surface investigation and review of existing conditions to determine soil make up, ground water level and location of below grade utilities.
Maintenance requirements should be carefully considered during design when choosing assets.
- Consider DEP’s green infrastructure maintenance guidelines in asset consideration.
- NYCHA property management staff and/or contractors must remove all trash from the drainage areas to promote uninterrupted drainage.
- Stormwater management partner must develop educational signage and maintenance cards to facilitate communication and maintenance requirements. These should be provided to property management during turnover and signs should be posted for staff and residents, so they are clearly visible and legible.
Surface area of rain gardens must be designed and constructed with no longitudinal or lateral slope. Parking lot or roadway runoff must not be directed to rain gardens. Rain gardens must be located 30 ft maximum from the downspout or impervious area treated.
Protect existing infrastructure:
- Avoid interference with NYCHA safety and security infrastructure including electrical conduits.
- Locate at least 10 feet from any building.
- Locate at least 25 feet from MTA sites.
- Rehabilitate existing curbs to guide water flow to the new infrastructure including underground storage and retention tanks.
All roofs, paved areas, yards, parking lots, playgrounds, etc. shall drain into a separate storm sewer system, or a combined sewer system, or to a place of disposal approved by the commissioner and in accordance with the requirements of DEP.
Storm water shall not be drained into sewers intended for sewage only.
Refer to Grounds/Excavation for excavation and backfilling requirements.

Stretch

Designers are encouraged to retain, infiltrate, and/or harvest the first inch of rainfall in a 24-hour period sitewide.
Installation of Reuse Systems may be considered. Reuse is the process of collecting rainfall or run off and storing it for eventual reuse in other applications.

RAD Conversions

Where DEP Green Infrastructure (“GI”) features, or “practices,” exist or are planned, RAD Conversions should coordinate their site design with these features. The RAD Conversions will be required to meet certain requirements for non-interference with any pre-existing green infrastructure installed by the NYC Department of Environmental Protection. The RAD Conversions will also be required to provide access and otherwise cooperate with any green infrastructure projects that are planned, designed, or in construction at the time of construction closing. NYCHA will provide the location of existing and planned green infrastructure projects along with design documents as they are available.
